Error in sample_without_replacement with Numba 0.43.0

[oyamad]

>>> qe.random.sample_without_replacement(5, 3)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

TypeError: 'NoneType' object cannot be interpreted as an integer

This used to work fine in Numba 0.42.1.

It seems that the conditional statement "num_trials is None" is not working properly in Numba 0.43.0.
